Expression: \$9^5 \times 9^8\$.

Given expression

\$9^5 \times 9^8\$.

Apply the product rule for exponents:\$(a^m \times a^n) = a^m+n\$

\$9^5 \times 9^8 \$ ⇒ \$9^(5+8)\$

Add the exponents:

\$9^5 \times 9^8 = 9^13\$

Therefore, the solved expression is \$9^13\$.

This option is incorrect because it incorrectly adds an extra 2 to the exponent sum, which should be 5 + 8

\$9^15\$

This option is incorrect because it incorrectly adds an extra 4 to the exponent sum, which should be 5 + 8

\$9^17\$

This answer is correct because the result of the expression is \$9^13\$

\$9^13\$

This option is incorrect because it incorrectly subtracts 2 from the exponent sum, which should be 5 + 8

\$9^11\$

Option

C
